Specification forming part of Letters Patent No. 126,119, dated April23, 1872 g antedated April 18, 1872.

To all whom it may concern:

Be it kno-wn that I, ROBERT WHITEHILL, of the city, county, and State ofNew York, have invented a new and useful Improvement in Take-up Devicesfor Shuttles; and I do hereby declare that the following is a full,olea-r, and exact description of the same, reference being had to theaccompanying drawing forming part of this speciticatiou, and in which-Figures 1 and 2 represent plan views of a shuttle in different positionsof its throw to illustrate the action of'my improved take-up as appliedthereto. Fig. 3 is a horizontal vertical section at the line x in Fig l.

Similar letters of reference indicate corresponding parts throughout theseveral igures of the drawing.

My invention relates to the shuttles of looms used for weaving corsetsand other articles or work," in which the number of warp-yarns raisedand lowered to open and close the shed is varied, during the progress ofthe work, so as to change the width of the shed. The invention consistsin a take-up roller constructed or provlded with an eye or guide for theweftyarn as it comesfrom the quill to pass through, and so that saidtake-up, which is an attachment to the shuttle, prevents no obstructionto the draft on said yarn, but is operated by frictional contact withthe warp to take up and let out again, in a uniform manner, the surplusweft-yarn drawn from the quill by the throw of the shuttle over orbeyond the width of the shed.

Referring to the accompanying drawing, A represents the body of theshuttle; B, its quill; and C, a brace-plate attached to or forming partof the shuttle, and arranged to travel over and in close proximity tothe warpyarns. The take-up is arr. nged upon this plate; and consistsmainly of a horizontal roller, D, having its axis transversely disposedl to the path of the shuttle, and carried on its from the quill B,through an end guide, f, and

from thence through the eye cin the roller, from whence it passesthrough a tube or guide, g, on the lever E, which latter has a roller orbearing, h, on the side of the fulcrum b, opposite that on which isarranged the roller D, for the purpose of holding up the .latter as itpasses through the shed and preventing its rotation, by contact of theroller or bearing l1., with the under surface of the warp-yarns thatcompose the shed.

A take-up thus constructed allows of the free', draft of the weft-yarnfrom oft' the quill through the eye in the roller D, without anyrotation of the latter taking place, while the shuttle passes throughthe shed, but in its travel beyond the shed in either direction theroller D is rotated by frictional contact with the warp to wind up theweft-yarn c drawn from the quill during such prolonged travel of theshuttle, and inthe return of the latter toward the shed to pay out suchsurplus weft4 by the unwinding of the same from said roller. In this waythere is no unequal strain or tension on the weft-yarn, but the slack istaken up and given out again in a uniform and easy manner by the merefriction of the roller D in passing over the warp, and there is nointerference with the draft from the quill, which hy the take-uplheredescribed is kept free from entanglement by the weft-yarn. Fig. 1 of thedrawing represents the shuttle as' at the end of its throw immediatelyprevious to commencing its return travel, and Fig, 2 shows the shuttleas passing through the shed, with the'wei't-yarn c wound upon the rollerD,preparatoryto paying out the same in the completion of its throw.

What is here claimed, and desired to be secured by Letters Patent, is-

l. The combination, with the shuttle, of a take-up roller provided withan eye or guide for passage of the weft-yarn, and arranged so as to beoperated by i'rictional contact with the warp to wind and unwind saidyarn during the throw of the shuttle7 substantially as specified.

2. The combination with such roller D, ap plied to a shuttle, of thelever E and the roller or bearing/L, arranged to operate substantiallyas described.
